1. A system comprising: an electrode; a computing device comprising a processor in communication with the electrode; and a non-transitory, computer-readable medium in communication with the processor and storing instructions that, when executed by the processor, cause the processor to perform operations comprising: a sequence of stimuli comprised of a stimulus element or a plurality of stimulus elements: a set of sequences of stimuli: presenting a first sequence of stimuli to: (i) a first set of subjects associated with a first selection criteria and (ii) a second set of subjects associated with a second selection criteria; detecting a first set of voltage fluctuation sequences, the first set of voltage fluctuation sequences comprising a sequence of voltage fluctuations from each of the first set of subjects; detecting a second set of voltage fluctuation sequences, the second set of voltage fluctuation sequences comprising a sequence of voltage fluctuations from each of the second set of subjects; determining, by a neural network, a pattern of voltage fluctuations characteristic of the first set of voltage fluctuation sequences and not characteristic of the second set voltage fluctuation sequences; providing a recommendation for a selection of subjects from among a third set of subjects based on the pattern of voltage fluctuations; presenting, by the sensory presentation device, the set of sequences of stimuli to the first set of subjects; determining, by the neural network, a respective correlation value for each of the set of sequences of stimuli, selecting, by the first computing device, the first sequence of stimuli from among the set of sequences of stimuli based on the respective correlation value for the first sequence of stimuli, presenting a first sequence of stimuli to: (i) a fourth set of subjects associated with a fourth selection criteria and (ii) said second set of subjects associated with a fourth selection criteria; detecting a fourth set of voltage fluctuation sequences, the fourth set of voltage fluctuation sequences comprising a sequence of voltage fluctuations from each of the fourth set of subjects; presenting said second set of voltage fluctuation sequences, the second set of voltage fluctuation sequences comprising a sequence of voltage fluctuations from each of said second set of subjects; determining, by a neural network, a pattern of voltage fluctuations characteristic of the fourth set of voltage fluctuation sequences and not characteristic of the second set voltage fluctuation sequences; providing a recommendation for a selection of subjects from among a further set of subjects based on the pattern of voltage fluctuations; presenting, by the sensory presentation device, a set of sequences of stimuli to the fourth set of subjects; determining, by the neural network, a respective correlation value for each of the set of sequences of stimuli, selecting, by the fourth computing device, the fourth sequence of stimuli from among the set of sequences of stimuli based on the respective correlation value for the fourth sequence of stimuli.

3. The system of claim 1 wherein some of the stimulus elements of a sequence of stimuli are selected for replacement or modification according to the respective correlation value for each of the set sequences of stimuli to maximize the respective correlation value.

4. The system of claim 1 , wherein the sequence of stimuli or the set of sequence stimuli is standardized for more than one selection criteria for test subjects.
